CTDUMP(1) General Commands Manual CTDUMP(1)

NAME

ctdump — print the metadata, history and user attributes of a CTSim file

SYNOPSIS

ctdump file [OPTIONS]

DESCRIPTION

ctdump prints what is known about file: its format and content type, its dimensions, the scanner geometry of a projection file or the axis extent and statistics of an image, the history of the operations that produced it, and any user attributes.

The history is the useful part. Each entry records the operation that was performed and the parameters it was given, so two files can be compared by what made them rather than by reading prose. Files written before version 6.5.0, and files in the legacy format, carry the history as a single line of text, which is printed as such.

Both the HDF5 and legacy formats are understood. h5dump(1) will show the raw structure of an HDF5 file; ctdump interprets CTSim's own schema.

Every tool is run through ctsim-nogui, as in "ctsim-nogui ctdump ...", or directly if a symbolic link of that name points at it.

The arguments and options are as follows:

file
Image (.if) or projection (.pj) file, either format
Omit the history detail
Print only the compute time of the last operation, in seconds
Report progress and details while running.
Print the CTSim version and exit.
Print the usage summary and exit.
